Leswing, Saddle Brook, N.J., and Fred Wasser, 45 Wickes Ave., Yonkers, N.Y. Filed Dec. 3, 1959, Ser. No. 857,122 7 Claims. (CI. 20-53) This invention relates to casement windows and more especially to a casement window construction which makes it possible to shift a casement window sash into different positions for better ventilation and for washing both sides of the casement window from inside the house.

One of the advantages of double-hung sash has been the greater convenience when washing the outside of the windows. With casement windows there has been no convenient way to reach the outside of the sash; and where such windows are high off the ground, ladders have been used when washing them.

It is an object of this invention to provide an improved casement window with a support on which the sash can swing into position to make both sides accessible to a window washer standing within the building. The support on which the sash is movable, to make both side accessible, is a part of the sash assembly which swings on the usual hinged connection of the sash to the window frame.

To all appearances, the window of this invention is an ordinary casement window, and the improvements require little additional structure.

Another disadvantage of casement windows has been that they shut off air when a breeze is coming from the side of the window to which the sash is hinged. The swinging sash of this invention can be adjusted to deflect air from either side into the room.

It is another object of the invention to provide an improved casement window, of the character indicated, with simple and rugged supporting means and pivotal connections that are convenient to operate and inexpensive to manufacture.

Other objects, features and advantages of the invention will appear or be pointed out as the description proceeds.

In the drawing:

FIGURES 2 and 3 are views similar to FIGURE 1 but showing the window sash in different positions;

FIGURE 5 is a fragmentary sectional view, similar to FIGURE 4, but taken in a plane parallel to the outer face of the window sash, with the sash removed;

FIGURE 6 is an enlarged, fragmentary, detail view showing a latch for holding the sash in fixed relation to the swinging support by which the sash is carried; and

FIGURE 7 is a greatly enlarged sectional view taken on the line 77 of FIGURE 6.

FIGURE 1 shows a building 10 having a window opening 12 which contains a window frame 14.

A sash 16 is connected by pivots 18, best shown in FIGURE 4, to top and bottom links 21 and 22, respectively, of a sash support 24.

This sash support 24 has the top link 21 and bottom link 22 connected to one another at one side by a connection 26 (FIGURES 2 and 5); and the links 21 and 22 are preferably of one-piece construction with this connection 26.

There are bearings 30 in the links 21 and 22 for receiving the pivots 18 of the window sash. The pivots are free to rotate in these bearings 30 to the extent permitted by flanges 32 (FIGURE 4) at the outside of the window sash 16. These flanges extend for the full width of the window sash and they cover the links 21 and 22 so that the links are not visible from outside the window.

Since the bearings 30 are located adjacent to the ends of the links 21 and 22, the flanges 32 of the window sash 16 can swing around the ends of the links 21 and 22, as shown in FIGURES 2 and 3. This swinging movement is somewhat less than when the window is equipped with an opener 35. Such openers, which are conventionally used with casement windows, have a link 36 for holding the window sash at the desired degree of opening;

In the embodiment of the invention shown in the drawing, the link 36 of the opener is connected with the bot tom link 2 of the window instead of being connected directly to the sash. This connection includes a lug 38 on the bottom link 22, and a pivot 40.

' The links 21 and 22 and their connection 26 are preferably made of metal with a degree of resilience so that the outer ends of the links 21 and 22 can be sprung apart far enough to receive the pivots 18 of the window sash 16. This makes it practical to have the pivots 18 of onepiece construction with the window sash, as shown in FIGURE 4.

In order to have the sash remain in any selected angular position, without introducing complication into the construction, the links 21 and 22 and their connection 26 are preferably constructed so that the end faces of the bearings 30 exert a spring pressure against the frame of the window sash and thus provide friction for holding the sash against swinging movement under ordinary conditions. The friction is not sufficient, however, to prevent the window from being moved manually about the pivots 18 whenever an occupant of the building wishes to change the position of the sash, either for washing the outside surface or merely changing the ventilation of the room. This shifting of the window sash, to deflect air from either direction along the side of the building, is an additional advantage of the invention, and is a result which is not possible with conventional casement windows.

The window opener 35 is attached to the frame 14 and is operated by a crank 46. The construction is conven- ,tional and well understood in the art. No illustration or further description of it is necessary for a complete understanding of this invention. 4

The support 24 is connected to the window frame 14 by pivots 48 and '49 (FIGURE 5) at the upper and lower ends, respectively, of the connection 26. Each of the pivots 48 and 49 extends into a bearing 50 in the link 21 1 or 22, and these bearings 50 have their axes in alignment with one another and parallel to the axes of the bearings 30.

The pivot 48 is a stud extending from a plate 52 attached to the window frame 14 by screws 54. These screws are merely representative of fastening means for securing the plate 52 and the pivot 48 in a fixed position on the window frame 14. The pivot 49 is similarly connected to the window frame 14 by a plate 52 and screws 54.

There is a latch 61 on the sash 16 for holding the window closed. This latch 61 is conventional. Because of the swinging movement of the sash 16 on the support 24, however, the window of this invention requires another latch 62 for holding the sash in a fixed relation to the support.

FIGURES 6 and 7 show the construction of the latch 62. It includes a frame 64 secured to the sash 16 by fas tening means, such as screws 65. A bolt element 66 slides in the frame 64 and is moved back and forth manually by a handle 68 extending through a slot 70 in the frame 64.

The slot 70 is of such length that movement of the handle 68 to the rearward end of the slot retracts the forward end of the bolt element 66 within the frame 64 and leaves the sash 16 free to swing with respect to the support 24. Movement of the handle 68 in the opposite direction 3 advances the forward end of the bolt element into a rim socket 72 attached to the support 24. Thus, with the bolt element pushed forward, the sash 16 and the support 24 are locked together and swing as a unit.

The preferred embodiment of the invention has been illustrated and described, but changes and modifications can be made and some features can be used in different combinations without departing from the invention as defined in the claims.

What is claimed is:
